Max speed of SPI

[nagamaheshg]

We are testing SPI interface using spidev on i.MX6dl, need to check the max speed of SPI which I have set to 50Mhz in dst files.

When we set the max clock speed in our program above 30Mhz there is no effect on the clock speed, it is capped @30Mhz.

Is this a limitation ?

Hi Nagamahesh

i.MX6SDL Datasheet
